- PROCESS OF MAKING PAPER OUT OF PEAT.

Application filed April 23, 1926 Serial No. 104,150.

This invention appertains to a novel process for making paper, card and wall board and the like out of peat.

Theprimary object of the present invention is the provision of a novel process for making paper out of peat embodying means for reducing the peat into shreds by a suitable machine and combining the shredded peat with rags or the like ground in a suitable great strength and constitute an integrally bound structure.

With these and other objects in view, the invention consists in the novel steps and the process of forming the peat.

In Figure 1 ofthe drawings is shown a front elevation of a particular type of machine used in one step of the process for forming the shredded peat,

Figure 2 is a longitudinalsection through thesame,

igure 3 is a perspective view of a fragment of a wall board formed from the peat,

Figure 4 is a side elevation of a preferred type of beater, grinder and washing machine used in my invention,

Figure 5 is a top plan view of the same,

Figure 6 is a side elevation of the same looking in the opposite direction from Figure 4, and

Figure 7 is an end elevation'of the same.

The process embodies the use of peat of the best grade preferably taken from one and one-half feet below the surface of the marsh or bog and two feet from the bottom therefrom. The peat is taken in its natural state from the bog and placed in a special type of shredding machine, so that the same will be 59 torn into shreds or fibers. As shown, the

shredding machine comprises a circular casing 5 including the inner and outer sections 6 and '2' having abutting flanges 8 which are suit-ably connected by suitable bolts 9.' This casing 5 is supported by suitable brackets 10 which are bolted to a supporting standard 11. Arranged in spaced relation to the standard 11 is a similar standard 12 and the upper ends of these standards ll and 12 are provided with bearings 13 for the reteption of an operating shaft 14 which extends into the casing 5. Keyed or otherwise secured to the shaftl l is a pulley wheel 15 for permitting the shaft to be driven from any suitable source of power. Rotatably mounted within the casing Ff is a suitable wheel or disk 16, one face of which has threaded therein teeth 17. The teeth are preferably arranged in annular concentric rows. Rigidly secured to the outerwall of the casing 5 are inwardly directed shredding teeth 18 for cooperation with the shredding teeth 17 carried by the disk 16. The teeth 18 are also preferably arranged in spaced concentric annular rows which are arranged intermediate the rows of teeth 17. The outer wall of the casing 5 at one side of the axis thereof is provided with a suitable hopper or spout 19 for facilitating the feeding of the peat into the casing between the outer wall and the disk 16. The lower end of the casing is provided with an outlet opening 20 to permit the removal of the shredded peat therefrom. In use of the improved shredding machine the blocks of peat are fed into the casing through the spout or hopper L 19 and the teeth 17 and 18 will tear the peat into elongated shreds.

This shredded pea-t is combined with a byproduct, which formsthe second step of the method. This by-product can consist of old rags, gunnysacks or cooked whole oats. It is preferred to use old rags as it is found that the same will combine more readily with the peat and give greater strength thereto. The rags are out into pieces and are then introduced into abeater, grinder and washing machine of substantially the type shown in Pat- I cut No. 859,972 issued July 16, 1907. The

preferred type of this machine is illustrated p in Figures 4 to 7 inclusive and includes substantially an oval tank 25 divided longitudinally by a midfeather or partition 26 on one side of which is situated an adjustable roll 27 carrying bearing knives 28 for cooperation with a bed plate 29. This roll can be raised by suitable mechanism indicated by the referof the tank. After the rags have been reduced to substantially half stuff the shredded peat is introduced into the feeder. After the peat has been thoroughly mixed with the half stuff, the surplus water is drained from the mixture and a suitable sizing rosin and alum is introduced therein. This mixture is now run into boards by a suitable paper machine. I prefer to use substantially seventy-five parts of peat to twenty five parts of the half stufi. However this proportion can be varied from seventy to seventy five parts of peat to thirty to twenty five parts of the half stufi without any noticeable di-fl'erence in the quality of the mixture. The amount of alum and rosin used may vary according to the mixture but ten pounds of rosin and alum can be used to every tion, but

What I claim as new is:

-The process of making paper out of peat consisting, first, of tearing the peat in its natural state into fiber; second, cutting rags into clippings; third, introducing the clippings into a combined beater, grinder and washing machine to form a half stufi fourth, introducing substantially seventy-five parts of peat fiber into the machine for every twenty-five parts of half stuif contained therein; fifth, draining the surplus Water from the mixture; sixth, adding rosin-and alum to the mixture, and seventh, drawing the mixture off and running the same into sheets.

In testimony whereof I aflix by signature.
